I have a set of the heads in question. Bought them bare cnc'd. Then i bought there corresponding valves as well. Trying to get any information about these heads from procomp is worthless, at least in my experience. They're basically identical to the victors from what i here, with the exception of no heli-coiled bolt holes. The set i have has 2.25 intake with 1.81 exhaust valve diameter. Throat is opened to 90% from procomp. Valves from them are 5.5" OAL, might be to long havent put rockers on them yet, or down a valve job. Which was horrible btw. Guide clearance was good though. Feel free to ask questions.
